[0059] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0060] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. "First", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0061] A typical OLED display substrate includes a base substrate, a driving circuit arranged on the base substrate, a planar layer arranged on a side of the driving circuit away from the base substrate, an anode arranged on a side of the planar layer away from the base substrate, a light-emitting layer arranged on a side of the anode away from the base substrate, and a cathode arranged on a side of the light-emitting layer away from the base substrate.

[0062] The driving circuit on the substrate substrate usually includes a signal line made of a source-drain metal layer, for example, a data line (Data line) for transmitting or writing data and a power line (VDD line) for transmitting a driving voltage. Before preparing the anode on the side of the driving circuit away from the substrate substrate, it is necessary to prepare a flat layer (PLN) on the driving circuit, and then prepare the anode on the flat layer, so that the anode prepared subsequently has a higher flatness. However, in order to achieve high resolution, the pixel size of the OLED display substrate is small and the signal lines are relatively dense; and in order to ensure the life and display brightness of the OLED display substrate, the area of ​​the effective light-emitting area of ​​each pixel needs to be as large as possible. Therefore, the signal line of the driving circuit will inevitably be arranged under the anode, that is, the signal line of the driving circuit will overlap with the anode. At this time, since the signal line made of the source-drain metal layer is relatively thick, and the flat layer on the signal line made of the source-drain metal layer cannot make it completely flat, the anode on the flat layer and the light-emitting layer on the anode are uneven, and the anode and the light-emitting layer on the anode have asymmetric protrusions, which causes color deviation when observed from the left and right sides of the normal line of the display substrate at the same angle as the normal line of the display substrate.

[0063] Figure 1 A schematic diagram of an OLED display substrate. Figure 2 FIG. 1 is a cross-sectional schematic diagram of a sub-pixel in an OLED display substrate. Figure 1 and 2 As shown, the OLED display substrate includes: a base substrate 10, a pixel driving circuit 20, a planar layer 30, an anode 40, a light-emitting layer 50, a cathode 60 and a pixel defining layer 80; the pixel defining layer 80 defines an effective light-emitting area 90, for example, a blue effective light-emitting area 91, a red effective light-emitting area 92 and a green effective light-emitting area 93; the driving circuit 20 includes a signal line group 25 made of a source-drain metal layer. Figure 1 2 shows the positional relationship between the signal line group 25 and the effective light emitting area 90. Figure 1 As shown, the signal line group 25 includes a data line 251 for transmitting or writing data and a power line 252 for transmitting a driving voltage. Since the size of the effective light-emitting area 90 in the extension direction of the data line 251 is larger than the size in the direction perpendicular to the extension direction, the effective light-emitting area 90 can usually only cover one signal line group 25. Figure 2As shown, due to the large thickness of the signal line group 25, the flat layer 30 covering the signal line group 25 cannot completely flatten the display substrate, resulting in the anode 40 on the flat layer 30 and the light-emitting layer 50 on the anode 40 being uneven, so that the anode 40 and the light-emitting layer 50 on the anode 40 have asymmetric protrusions 70. The asymmetric protrusion 70 is asymmetric relative to the center of the effective light-emitting area 90 defined by the pixel defining layer 80. The asymmetric protrusion 70 emits different light to the left and right sides of the normal of the display substrate, resulting in a color shift phenomenon when the left and right sides of the normal of the display substrate are observed at the same angle to the normal of the display substrate. For example, the color of the display substrate observed from the left side of the normal of the display substrate at an angle of 30 degrees to the normal of the display substrate is different from the color of the display substrate observed from the right side of the normal of the display substrate at an angle of 30 degrees to the normal of the display substrate, resulting in the above-mentioned color shift phenomenon.

[0064] In this regard, the embodiments of the present disclosure provide a display substrate and a display device. The display substrate includes a base substrate, a plurality of sub-pixel groups, and a plurality of signal line groups. The plurality of sub-pixel groups and the plurality of signal lines are arranged on the base substrate; the plurality of signal line groups are arranged in intervals along a first direction, each signal line group includes at least one signal line, the signal line extends along a second direction intersecting the first direction, each sub-pixel group includes a first sub-pixel, the first sub-pixel includes a first anode, and the first anode overlaps with two adjacent signal line groups. Since the first anode overlaps with two adjacent signal line groups, even if the first anode forms two protrusions at the position where it overlaps with the two adjacent signal line groups, the two protrusions can reduce the asymmetry of the light emission of the first anode and the light-emitting layer on the first anode, and can even eliminate the asymmetry of the light emission of the first anode and the light-emitting layer on the first anode, thereby improving or even eliminating the color deviation of the viewing angle.

[0065] The display substrate and the display device provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0066] Figure 3 FIG. 1 is a layout diagram of a display substrate provided according to an embodiment of the present disclosure.

The first anode 1110 of the first sub-pixel 111 may further include a first connecting electrode 171 connected to the first main body 1112; the first connecting electrode 171 is configured to connect the first main body 1112 to the pixel driving circuit 220 corresponding to the first sub-pixel 111. When the display substrate includes the second sub-pixel 112, as shown in FIG. Figure 3As shown, the second anode 1120 of the second sub-pixel 112 may further include a second connection electrode 172 connected to the second main body 1122; the second connection electrode 172 is configured to connect the second main body 1122 to the pixel driving circuit corresponding to the second sub-pixel 112.

Figure 4 An equivalent circuit diagram of a pixel driving circuit of a sub-pixel in a display substrate provided according to an embodiment of the present disclosure. Figure 4 The pixel driving circuit shown can be used for any one of the first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 described above.

The gate line GL is used to transmit a gate signal and may include a first gate line GLn and a second gate line GLn-1; the emission control line EM may transmit a control signal. Thus, the pixel driving circuit is a 7T1C pixel driving circuit. Of course, the embodiments of the present disclosure include but are not limited to this, and the first sub-pixel, the second sub-pixel and the third sub-pixel mentioned above may also adopt other types of pixel driving circuits.

The first drain electrode D1 of the first thin film transistor T1 is connected to the third source electrode S3 of the third thin film transistor T3 and the sixth source electrode S6 of the sixth thin film transistor T6.

[0070] For example, Figure 4 As shown, the second gate G2 of the second thin film transistor T2 is connected to the first gate line GLn, the second source S2 of the second thin film transistor T2 is connected to the data line 121, and the second drain D2 of the second thin film transistor T2 is connected to the first source S1 of the first thin film transistor T1.

[0071] For example, Figure 4 As shown, the third gate G3 of the third thin film transistor T3 is connected to the first gate line GLn, the third source S3 of the third thin film transistor T3 is connected to the first drain electrode D1 of the first thin film transistor T1, and the third drain D3 of the third thin film transistor T3 is connected to the first gate G1 of the first thin film transistor T1.

[0072] For example, Figure 4 As shown, the fourth gate G4 of the fourth thin film transistor T4 is connected to the second gate line GLn-1, the fourth source S4 of the fourth thin film transistor T4 is connected to the initialization line RL, the fourth drain D4 of the fourth thin film transistor T4 is connected to the first gate G1 of the first thin film transistor T1, and the initialization voltage Vint is applied through the initialization line RL.

[0073] For example, Figure 4 As shown, the fifth gate electrode G5 of the fifth thin film transistor T5 is connected to the emission control line EM, the fifth source electrode S5 of the fifth thin film transistor T5 is connected to the power line 122, and the fifth drain electrode D5 of the fifth thin film transistor T5 is connected to the first source electrode S1 of the first thin film transistor T1.

[0074] For example, Figure 4 As shown, the sixth gate G6 of the sixth thin film transistor T6 is connected to the emission control line EM, the sixth source S6 of the sixth thin film transistor T6 is connected to the first drain D1 of the first thin film transistor T1, and the sixth drain D6 of the sixth thin film transistor T6 is connected to the anode of each sub-pixel (for example, the first anode, the second anode or the third anode mentioned above).

[0075] For example, Figure 4As shown, the seventh gate G7 of the seventh thin film transistor T7 is connected to the second gate line GLn-1, the seventh source S7 of the seventh thin film transistor T7 is connected to the anode of each sub-pixel, and the seventh drain D7 of the seventh thin film transistor T7 is connected to the fourth source S4 of the fourth thin film transistor T4.

[0076] For example, Figure 4 As shown, the capacitor CSt includes a first electrode CE1 and a second electrode CE2, the second electrode CE2 is connected to the power line 122, and the first electrode CE1 is connected to the first gate electrode G1 of the first thin film transistor T1 and the third drain electrode D3 of the third thin film transistor T3.

[0077] The following will Figure 4 A working mode of the pixel driving circuit shown is schematically described. First, when a reset signal is transmitted to the second gate line GLn-1 and the seventh thin film transistor T7 is turned on, the residual current flowing through the anode of each sub-pixel is discharged to the fourth thin film transistor T4 through the seventh thin film transistor T7, thereby suppressing the luminescence caused by the residual current flowing through the anode of each sub-pixel. Then, when an initialization signal is transmitted to the second gate line GLn-1 and an initialization signal is transmitted to the initialization line RL, the fourth thin film transistor T4 is turned on, and the initialization voltage Vint is applied to the first gate G1 of the first thin film transistor T1 and the second electrode CE2 of the capacitor Cst through the fourth thin film transistor T4, so that the first gate G1 and the capacitor Cst are initialized. The initialization of the first gate G1 can turn on the first thin film transistor T1. It should be noted that the above-mentioned reset signal and the above-mentioned initialization signal can be the same signal.

[0078] Subsequently, when a gate signal is transmitted to the first gate line GLn and a data signal is transmitted to the data line 121, the second thin film transistor T2 and the third thin film transistor T3 are turned on, and the data voltage Vd is applied to the first gate electrode G1 through the second thin film transistor T2, the first thin film transistor T1, and the third thin film transistor T3. At this time, the voltage applied to the first gate electrode G1 is the compensation voltage Vd+Vth, and the compensation voltage applied to the first gate electrode G1 is also applied to the first electrode CE1 of the capacitor Cst.

[0079] Subsequently, the power line 122 applies the driving voltage Vel to the second electrode CE2 of the capacitor Cst and applies the compensation voltage Vd+Vth to the first electrode CE1, so that charges corresponding to the difference between the voltages respectively applied to the two electrodes of the capacitor Cst are stored in the capacitor Cst, and the first thin film transistor T1 is turned on for a predetermined time.

[0080] Subsequently, when an emission control signal is applied to the emission control line EM, the fifth thin film transistor T5 and the sixth thin film transistor T6 are both turned on, so that the fifth thin film transistor T5 applies the driving voltage Vel to the first thin film transistor T1. When the driving voltage Vel passes through the first thin film transistor T1 turned on by the capacitor Cst, the driving current Id corresponding to the difference between the driving voltage Vel and the voltage applied to the first gate G1 through the capacitor Cst flows through the first drain electrode D1 of the first thin film transistor T1, and the driving current Id is applied to each sub-pixel through the sixth thin film transistor T6, so that the light-emitting layer of each sub-pixel emits light.

The pixel driving circuit 220 includes the above-mentioned thin film transistors T1, T2, T3, T4, T5, T6 and T7, gate lines GLn, GLn-1 connected to the plurality of thin film transistors T1, T2, T3, T4, T5, T6 and T7, emission control lines EM, initialization lines RL, data lines 121 and power lines 122 and capacitors Cst. Figures 5A-5E The structure of the pixel driving circuit 220 will be described.

[0082] For example, Figure 5A The semiconductor layer 310 of the pixel driving circuit 220 is shown. The semiconductor layer 310 can be formed by patterning a semiconductor material. The semiconductor layer 310 can be used to make the active layers of the above-mentioned thin film transistors T1, T2, T3, T4, T5, T6 and T7, and each active layer can include a source region, a drain region and a channel region between the source region and the drain region. For example, the semiconductor layer 310 can be made of amorphous silicon, polycrystalline silicon, oxide semiconductor materials, etc. It should be noted that the above-mentioned source region and drain region can be regions doped with n-type impurities or p-type impurities.

[0083] In the display substrate provided in the embodiment of the present disclosure, a gate insulating layer (not shown) is formed on the semiconductor layer to protect the semiconductor layer. Figure 5B 2 shows a first conductive layer 320 of the pixel driving circuit 220, which is disposed on the gate insulating layer so as to be insulated from the semiconductor layer 310. The first conductive layer 320 may include a first electrode CE1 of the capacitor Cst, gate lines GLn, GLn-1, an emission control line EM, and gates of thin film transistors T1, T2, T3, T4, T5, T6, and T7 (e.g., the first gate G1, the second gate G2, the third gate G3, the fourth gate G4, the fifth gate G5, the sixth gate G6, and the seventh gate G7). Figure 5BAs shown, the gates of the thin film transistors T2, T4, T5, T6 and T7 are the overlapping portions of the gate lines GLn, GLn-1 and the semiconductor layer 310, the thin film transistor T3 may be a thin film transistor with a dual-gate structure, one gate of the thin film transistor T3 may be the overlapping portion of the gate line GLn and the semiconductor layer 310, and the other gate of the thin film transistor T3 may be a protrusion protruding from the gate line GLn; the gate of the thin film transistor T1 may be the first electrode CE1.

[0084] In the display substrate provided by the embodiment of the present disclosure, an insulating layer (not shown) is formed on the first conductive layer to protect the first conductive layer. Figure 5C The second conductive layer 330 of the pixel driving circuit 220 is shown, and the second conductive layer 330 includes a second electrode CE2 of the capacitor Cst and an initialization line RL. The second electrode CE2 at least partially overlaps with the first electrode CE1 to form a capacitor Cst.

[0085] In the display substrate provided by the embodiment of the present disclosure, a first protective layer (not shown) is formed on the second conductive layer to protect the second conductive layer. Figure 5D The third conductive layer 340 of the pixel driving circuit 220 is shown. The third conductive layer 340 includes the data line 121 and the power line 122 . Figure 5E Schematic diagram of the stacking position relationship of the semiconductor layer 310, the first conductive layer 320, the second conductive layer 330 and the third conductive layer 340. Figure 5D and 5EAs shown, the data line 121 is connected to the source region of the thin film transistor T2 in the semiconductor layer 310 through the gate insulating layer, the insulating layer and at least one via hole (e.g., the first via hole 381) in the first protective layer. The power line 122 is connected to the source region of the corresponding thin film transistor T5 in the semiconductor layer 310 through the gate insulating layer, the insulating layer and at least one via hole (e.g., the second via hole 382) in the first protective layer. The power line 122 is connected to the second electrode CE2 in the second conductive layer 330 through at least one via hole (e.g., two third via holes 383) in the first protective layer. The third conductive layer 340 also includes a first connecting portion 341, a second connecting portion 342 and a third connecting portion 343. One end of the first connection portion 341 is connected to the drain region of the corresponding third thin film transistor T3 in the semiconductor layer 310 through the gate insulating layer, the insulating layer and at least one via hole (e.g., the fourth via hole 384) in the first protective layer, and the other end of the first connection portion 341 is connected to the gate of the first thin film transistor T1 in the first conductive layer 320 through the insulating layer and at least one via hole (e.g., the fifth via hole 385) in the first protective layer. One end of the second connection portion 342 is connected to the initialization line RL through a via hole (e.g., the sixth via hole 386) in the first protective layer, and the other end of the second connection portion 342 is connected to the drain region of the seventh thin film transistor T7 in the semiconductor layer 310 through the gate insulating layer, the insulating layer and at least one via hole (e.g., the seventh via hole 387) in the first protective layer. The third connection portion 343 is connected to the drain region of the sixth thin film transistor T6 in the semiconductor layer 310 through the gate insulating layer, the insulating layer and at least one via hole (e.g., the eighth via hole 388) in the first protective layer.

[0086] In the display substrate provided by the embodiment of the present disclosure, a second protective layer (not shown) is formed on the third conductive layer to protect the third conductive layer. The anode of each sub-pixel can be disposed on the second protective layer.

[0087] An embodiment of the present disclosure provides a display substrate. Figure 6 FIG. 1 is a schematic plan view of a display substrate provided according to an embodiment of the present disclosure. Figure 6As shown, the display substrate includes a base substrate 101, a plurality of sub-pixel groups 110 and a plurality of signal line groups 120. The plurality of sub-pixel groups 110 and the plurality of signal line groups 120 are arranged on the base substrate 101; the plurality of signal line groups 120 are arranged at intervals along a first direction; at least one signal line 1200 extends along a second direction intersecting the first direction; each sub-pixel group 110 includes a first sub-pixel 111, and the first sub-pixel 111 includes a first anode 1110; the first anode 1110 overlaps with two adjacent signal line groups 120. That is, the orthographic projection of the first anode 1110 on the plane where the signal line group 120 is located overlaps with the two adjacent signal line groups 120. It should be noted that in the display field, a pixel usually includes multiple sub-pixels that can display monochrome (such as red, green or blue) respectively. The display of different colors is achieved by controlling the proportion of sub-pixels of different colors. Therefore, the first sub-pixel mentioned above is a monochrome sub-pixel; in addition, the above-mentioned signal line group refers to a collection of at least part of the signal lines shared by the driving circuits of the same column of sub-pixels.

[0088] For example, Figure 6 As shown, the first sub-pixel 111 includes a first effective light-emitting area 1115, and the first anode 1110 includes a first main body 1112. The first main body 1112 at least partially overlaps with the first effective light-emitting area 1115. The size of the first main body 1112 in the first direction is greater than the size of the first main body 1112 in the second direction. The overlap of the first anode 1110 with the two adjacent signal line groups 120 may be the overlap of the first main body 1112 with the two adjacent signal line groups 120. In the display substrate provided by the embodiment of the present disclosure, since the first anode overlaps with the two adjacent signal line groups, the first anode may form two protrusions at the position where it overlaps with the two adjacent signal line groups. The two protrusions may reduce the asymmetry of the light emission of the first anode and the light-emitting layer on the first anode, or even eliminate the asymmetry of the light emission of the first anode and the light-emitting layer on the first anode, thereby improving or even eliminating the color shift phenomenon generated when the display substrate is viewed from the left and right sides of the normal line at the same angle as the normal line of the display substrate. It should be noted that the left and right sides of the normal line of the display substrate may be the two sides of the extension direction of the signal line group.

[0089] For example, Figure 3 As shown, the signal line group may be composed of a data line 121 and a power source 122 , and the first anode 1110 of the first sub-pixel 111 overlaps with two adjacent signal line groups.

[0090] Figure 7 FIG. 1 is a schematic diagram of the structure of another display substrate provided according to an embodiment of the present disclosure. Figure 7As shown, since the first anode 1110 overlaps with two adjacent signal line groups 120, two protrusions 170 are formed on the first anode 1110 at the position where the first anode 1110 overlaps with the two adjacent signal line groups 120. It can be seen that, compared with the case where there is only one protrusion, the two protrusions 170 can reduce the asymmetry of the light emitted by the first anode 1110 and the light-emitting layer on the first anode 1110, or even eliminate the asymmetry of the light emitted by the first anode and the light-emitting layer on the first anode, thereby improving or even eliminating the color shift phenomenon generated when the display substrate is observed from the left and right sides of the normal line of the display substrate at the same angle as the normal line of the display substrate.

[0091] For example, in some examples, the ratio of the size of the first main body 1112 in the first direction to the size of the first main body 1112 in the second direction is γ1, and the value range of γ1 is 1.2-3. Figure 6 As shown, the orthographic projections of the signal lines 1200 in the two signal line groups 120 overlapping the first anode 1110 on the base substrate 101 extend in the second direction and pass through the orthographic projections of the first anode 1110 on the base substrate 101. In other words, the signal lines in the two signal line groups overlapping the first anode extend and pass through the first anode, so that the protrusion formed by the first anode also passes through the first anode along the second direction.

[0092] For example, in some examples, such as Figure 6 As shown, each signal line 1200 may extend outside the display area of ​​the display substrate, and in this case, each signal line 1200 may include an end portion 1209 connected to an external driving circuit. For example, when the signal line is a data line, the signal line may include an end portion connected to a data driver.

[0093] For example, in some examples, the base substrate 101 may be a transparent substrate; for example, the base substrate 101 may be a glass substrate, a plastic substrate, a quartz substrate, etc. Of course, the embodiments of the present disclosure include but are not limited to this, and the material of the base substrate 101 can be selected according to actual conditions and needs.

[0094] For example, in some examples, such as Figure 6 and 7As shown, the first sub-pixel 111 includes a first effective light-emitting area 1115, and the first anode 1110 includes a first main body 1112. The first main body 1112 at least partially overlaps with the first effective light-emitting area 1115. The size of the first main body 1112 in the first direction is greater than the size of the first main body 1112 in the second direction. The positions of the two signal line groups 120 overlapping with the first anode 1110 are located at the two ends of the first main body 1112 in the first direction. At this time, since the positions of the two signal line groups 120 overlapping with the first anode 1110 are located at the two ends of the first main body 1112 in the first direction and do not pass through the center of the first main body 1112, the two protrusions 170 formed at the position where the first anode 1110 overlaps with the two adjacent signal line groups 120 have a high degree of symmetry, thereby improving or even eliminating the color shift phenomenon generated when observing from the left and right sides of the normal line of the display substrate at the same angle as the normal line of the display substrate. It should be noted that Figure 6 The first anode in FIG. 1 shows only the first main body portion.

[0095] For example, in some examples, such as Figure 6 and 7 As shown, the shape of the orthographic projection of the first main body portion 1112 on the base substrate 101 is substantially a long strip, and the extension direction of the first main body portion 1112 intersects with the second direction.

[0096] For example, in some examples, such as Figure 6 and 7 As shown, the extension direction of the first main body 1112 is substantially perpendicular to the second direction. It should be noted that the above-mentioned “substantially perpendicular” means that the angle between the extension direction of the first main body and the second direction is between 85-90 degrees.

[0097] For example, in some examples, such as Figure 6 and 7 As shown, the positions of the two signal line groups 120 overlapping the first anode 1110 are approximately axisymmetric about the first bisector of the first main body 1112, and the first bisector is parallel to the second direction. Figure 7 As shown, the first anode 1110 forms two symmetrical protrusions 170 at the position where it overlaps with two adjacent signal line groups 120. The two protrusions 170 can further effectively reduce the asymmetry of the light emitted by the first anode and the light-emitting layer on the first anode, or even eliminate the asymmetry of the light emitted by the first anode and the light-emitting layer on the first anode, thereby improving or even eliminating the color shift phenomenon caused when observing from the left and right sides of the normal to the display substrate at the same angle as the normal to the display substrate.

[0098] It should be noted that, since the signal line group includes at least one signal line, that is, there is a case where the signal line group includes multiple signal lines, the above-mentioned positions of the two signal line groups are roughly axisymmetric with respect to the first bisector of the first main body portion refers to the positions of the two signal line groups, not that the two signal line groups themselves are roughly axisymmetric with respect to the first bisector of the first main body portion. In addition, the position of the signal line group may be the geometric center of the signal line group, for example, the geometric center of the orthographic projection of the signal line group on the first main body portion.

[0099] For example, in some examples, such as Figure 6 As shown, in each signal line group 1200, the first signal line 121 and the second signal line 122 are arranged in sequence, and the arrangement order of the first signal line 121 and the second signal line 122 in two adjacent signal line groups 1200 is the same. Therefore, the above-mentioned two signal line groups are located at positions that are substantially axisymmetric with respect to the first bisector of the first main body portion, which refers to the positions of the two signal line groups, rather than the two signal line groups themselves being substantially axisymmetric with respect to the first bisector of the first main body portion.

[0100] For example, in some examples, such as Figure 6 As shown, two adjacent signal line groups 120 include a first signal line group 1201 and a second signal line group 1202 arranged along a first direction, the first signal line 121 in the first signal line group 1201 is located on a side of the second signal line 122 away from the second signal line group 1202, and the first signal line 121 in the second signal line group 1202 is located on a side of the second signal line 122 close to the first signal line group 1201.

[0101] For example, in some examples, such as Figure 6 As shown, the size of the first main body 1112 in the first direction is greater than the size of the first main body 1112 in the second direction. That is, the shape of the first main body 1112 is a long strip, such as a hexagon or an ellipse. Figure 1 As shown, since the size of a common anode in the second direction is larger than that in the first direction, it can usually only cover one signal line group; the size of the first main body of the first anode provided in the embodiment of the present disclosure in the first direction is larger than that of the first main body 1112 in the second direction, so that it can overlap with two adjacent signal line groups without changing the area. For example, the first main body 1112 provided in the embodiment of the present disclosure can be Figure 1 The main body of the corresponding anode in the display substrate shown is rotated 90 degrees.

[0102] For example, the size of the first main body 1112 in the first direction may range from 45 to 60 microns; the size of the first main body 1112 in the second direction may range from 15 to 30 microns. It should be noted that the above sizes are only illustrative examples, and the size of the first main body in the embodiment of the present disclosure may be determined according to the size and resolution of the actual product.

[0103] For example, in some examples, such as Figure 6 As shown, the shape of the first main body 1112 is roughly hexagonal or elliptical, and the long axis of the hexagonal symmetry or the long axis of the ellipse is roughly parallel to the first direction. It should be noted that the above-mentioned "roughly parallel" means that the angle between the long axis of the hexagonal symmetry or the long axis of the ellipse and the first direction does not exceed 5 degrees.

[0104] It is worth noting that the embodiments of the present disclosure include but are not limited to this, and the shape of the first main body of the embodiments of the present disclosure may also be other long strips; in addition, when the shape of the first main body is approximately hexagonal or elliptical, and the long axis of symmetry of the hexagon or the long axis of the ellipse may not be parallel to the first direction, as long as the orthographic projection of the first anode on the plane where the signal line group is located overlaps with the two adjacent signal line groups.

[0105] For example, in some examples, such as Figure 7 As shown, the display substrate further includes a pixel defining layer 160, which is located on a side of the first anode 1110 away from the base substrate 101 and includes a first opening 161. The first sub-pixel 111 further includes a first light-emitting layer 1114, at least a portion of which is located in the first opening 161; the area defined by the first opening 161 is a first effective light-emitting area 1115. The first anode 1110 can drive the first light-emitting layer 1114 to emit light.

[0106] For example, Figure 7 As shown, the area of ​​the first effective light-emitting region 1115 may be slightly smaller than the area of ​​the first anode 1110, the shape of the first effective light-emitting region 1115 may be similar to the shape of the first main body 1112 of the first anode 1110, and the shortest distance between the edge of the first effective light-emitting region 1115 and the edge of the first main body 1112 is in the range of 1-5 microns.

[0107] It should be noted that the first light-emitting layer 1114 may include the electroluminescent layer itself and other functional layers located on both sides of the electroluminescent layer, such as a hole injection layer, a hole transport layer, an electron injection layer, and an electron transport layer.

[0108] For example, in some examples, such as Figure 7 As shown, the first sub-pixel 111 further includes a first cathode 1116 , and the first cathode 1116 is located on a side of the first light emitting layer 1115 away from the first anode 1112 .

[0109] For example, in some examples, such as Figure 7 As shown, the display substrate further includes: a flat layer 230, which is located between the film layer where the plurality of signal line groups 120 are located and the film layer where the first anode 1112 is located, and the height of each signal line group 120 in the direction perpendicular to the base substrate 101 ranges from 650 to 850 nanometers, and the thickness of the flat layer 230 ranges from 1.4 to 1.6 micrometers. Since the signal line group is usually made of a source-drain metal layer, and usually adopts a laminated structure, such as a Ti / Al / Ti laminated structure; therefore, the height (thickness) of each signal line group 120 in the direction perpendicular to the base substrate 101 is relatively large, and the flat layer 230 cannot completely flatten it, resulting in the first anode on the flat layer and the first light-emitting layer on the first anode being uneven, and the first anode and the first light-emitting layer on the first anode having convexities. At this time, the display substrate can effectively reduce the asymmetry of the light emission of the first sub-pixel, or even eliminate the asymmetry of the light emission of the first sub-pixel, thereby improving or even eliminating the color shift phenomenon generated when observing from the left and right sides of the normal line of the display substrate at the same angle as the normal line of the display substrate.

[0110] For example, in some examples, such as Figure 7 As shown, the display substrate further includes: a pixel driving circuit 220, the pixel driving circuit 220 is located between the base substrate 101 and the flat layer 230, and includes the above-mentioned signal line group 120. That is to say, the signal line group 120 can be a part of the pixel driving circuit 220, for example, the signal line group 120 can be a collection of signal lines formed by the source and drain metal layers in the pixel driving circuit 220. Of course, the pixel driving circuit in the embodiment of the present disclosure can refer to the usual design, for example, the pixel driving circuit can also include structures such as thin film transistors and capacitors, and the embodiment of the present disclosure will not be repeated here.

[0111] For example, in some examples, such as Figure 6 and 7 As shown, each signal line group 120 includes two signal lines 1200 , and the first anode 1110 overlaps with four signal lines 1200 in two adjacent signal line groups 120 .

[0112] For example, in some examples, such as Figure 6 and 7 As shown, at least one signal line 1200 included in each signal line group 120 includes a first signal line 121 and a second signal line 122, and the distance between the first signal line 121 and the second signal line 122 in one signal line group 120 is smaller than the distance between two adjacent signal line groups 120. At this time, since the distance between the data line 121 and the power line 122 in one signal line group 120 is smaller, the signal line group 120 will cause the first effective light-emitting area 1110 to form a protrusion 170 at a position overlapping with the signal line group 120.

[0113] It should be noted that the distance between the first signal line 121 and the second signal line 122 in one signal line group 120 may be the width of the interval between the first signal line 121 and the second signal line 122 in one signal line group 120. In addition, in an actual display substrate, due to the limitation of the design and manufacturing process of the pixel circuit, the first signal line is not a long and thin straight line with the same width everywhere, and the second signal line is not a long and thin straight line with the same width everywhere. The distance between the first signal line 121 and the second signal line 122 may be the average width of the interval between the first signal line 121 and the second signal line 122, and the distance between two adjacent signal line groups 120 may also be the average width of the interval between two adjacent signal line groups 120.

[0114] For example, in some examples, such as Figure 6 and 7 As shown, each signal line group 120 includes a data line 121 for transmitting a data signal and a power line 122 for transmitting a driving voltage, that is, the first signal line 121 can be a data line, and the second signal line 122 can be a power line 122 .

[0115] For example, in some examples, such as Figure 6 and 7 As shown, in a signal line group 120, the data line 121 and the power line 122 are arranged in sequence in the first direction, that is, from Figure 6 The data line 121 is arranged in sequence from the left side to the right side of the anode 1110. The data line 121 is located on the left side of the power line 122. The arrangement order of the data lines 121 and the power lines 122 in different signal line groups 120 is the same. Therefore, in the display substrate provided by the embodiment of the present disclosure, the positions of the two signal line groups overlapping the first anode 1110 are roughly axially symmetrical about the first bisector of the first anode 1110, rather than the two signal line groups themselves being roughly axially symmetrical about the first bisector of the first anode 1110.

[0116] For example, in some examples, such as Figure 6 and 7 As shown, when the signal line group 120 includes a plurality of data lines 1200, the plurality of data lines 1200 are arranged at intervals and are substantially parallel. For example, when the signal line group 120 includes a data line 121 and a power line 122, the data line 121 and the power line 122 are arranged at intervals and are substantially parallel.

[0117] For example, in some examples, the width of the data line 121 ranges from 2.5 to 3 microns, the width of the power line 122 ranges from 4 to 6 microns, and the distance between the data line 121 and the power line 122 ranges from 3 to 4 microns.

[0118] For example, in some examples, the interval between adjacent data lines is 23-35 microns; the interval between adjacent power lines is 23-35 microns; the length of the first main body 1112 along the first direction is 45-60 microns, so as to cover two adjacent signal line groups 120.

[0119] For example, in some examples, such as Figure 6 As shown, the first direction is perpendicular to the second direction.

[0120] For example, in some examples, such as Figure 6 As shown, each sub-pixel group 120 further includes a second sub-pixel 112 , and the second sub-pixel 112 includes a second anode 1120 . The second anode 1120 overlaps two adjacent signal line groups 120 .

[0121] In the display substrate provided by the embodiment of the present disclosure, since the second anode overlaps with two adjacent signal line groups, two protrusions can be formed on the second anode at the position where it overlaps with the two adjacent signal line groups. The two protrusions can reduce the asymmetry of the light emitted by the second anode and the light-emitting layer on the second anode, or even eliminate the asymmetry of the light emitted by the second anode and the light-emitting layer on the second anode, thereby further improving or even eliminating the color deviation phenomenon caused when observing from the left and right sides of the normal to the display substrate at the same angle as the normal to the display substrate.

[0122] Figure 8 FIG. 1 is a schematic diagram of the structure of another display substrate provided according to an embodiment of the present disclosure. Figure 8 As shown, since the second anode 1120 overlaps with two adjacent signal line groups 120, two protrusions 175 are formed on the second anode 1120 at the position where the second anode 1120 overlaps with the two adjacent signal line groups 120. It can be seen that, compared with the case where there is only one protrusion, the two protrusions 175 can reduce the asymmetry of the light emitted by the second anode 1120 and the light-emitting layer on the second anode 1120, or even eliminate the asymmetry of the light emitted by the second anode and the light-emitting layer on the second anode, thereby further improving or even eliminating the color shift phenomenon generated when observing from the left and right sides of the normal line of the display substrate at the same angle as the normal line of the display substrate.

[0123] For example, in some examples, such as Figure 6 As shown, the orthographic projections of the signal lines 1200 in the two signal line groups 120 overlapping the second anode 1120 on the base substrate 101 extend in the second direction and pass through the orthographic projection of the second anode 1120 on the base substrate 101 .

[0124] For example, in some examples, such as Figure 6 and 8As shown, the second sub-pixel 112 includes a second effective light-emitting area 1125, and the second anode 1120 includes a second main body 1122. The second main body 1122 at least partially overlaps with the second effective light-emitting area 1125. The size of the second main body 1122 in the first direction is greater than the size of the second main body 1122 in the second direction. The positions of the two signal line groups 120 overlapping with the second anode 1120 are located at the two ends of the second main body 1122 in the first direction. At this time, since the positions of the two signal line groups 120 overlapping with the second anode 1120 are located at the two ends of the second main body 1122 in the first direction, the two protrusions 175 formed at the position where the second anode 1120 overlaps with the two adjacent signal line groups 120 are highly symmetrical, thereby improving or even eliminating the color shift phenomenon generated when observing from the left and right sides of the normal line of the display substrate at the same angle as the normal line of the display substrate. It should be noted that Figure 6 The second anode in FIG. 1 only shows the second main body portion.

[0125] For example, in some examples, such as Figure 6 and 8 As shown, the shape of the orthographic projection of the second main body portion 1122 on the base substrate 101 is substantially a long strip, and the extension direction of the second main body portion intersects with the second direction.

[0126] For example, in some examples, such as Figure 6 and 8 As shown, the extension direction of the second main body portion is substantially perpendicular to the second direction.

[0127] For example, in some examples, such as Figure 6 and 8 As shown, the positions of the two signal line groups 120 overlapping the second anode 1120 are approximately axisymmetric about the second bisector of the second main body 1122, and the second bisector is parallel to the second direction. Figure 8 As shown, the second anode 1120 forms two symmetrical protrusions 175 at the position where it overlaps with the two adjacent signal line groups 120. The two protrusions 175 can further effectively reduce the asymmetry of the light emitted by the second anode and the light-emitting layer on the second anode, or even eliminate the asymmetry of the light emitted by the second anode and the light-emitting layer on the second anode, thereby further improving or even eliminating the color deviation phenomenon caused when observing from the left and right sides of the normal to the display substrate at the same angle as the normal to the display substrate.

[0128] For example, in some examples, such as Figure 6 As shown, the size of the second main body 1122 in the first direction is greater than the size of the second main body 1122 in the second direction. That is, the shape of the second main body 1122 is a long strip, such as a hexagon or an ellipse. Figure 1As shown, since the size of a conventional anode in the second direction is larger than that in the first direction, it can usually only cover one signal line group; the size of the second main body of the second anode provided in the embodiment of the present disclosure in the first direction is larger than that of the second main body in the second direction, so that it can overlap with two adjacent signal line groups without changing the area. For example, the second main body provided in the embodiment of the present disclosure can be Figure 1 The main body of the corresponding anode in the display substrate shown is rotated 90 degrees.

[0129] For example, in some examples, such as Figure 6 and 8 As shown, each signal line group 120 includes two signal lines 1200, and the second anode 1120 overlaps with four signal lines 1200 in two adjacent signal line groups 120. For example, the size of the first main body 1112 in the first direction may range from 45 to 55 microns; the size of the first main body 1112 in the second direction may range from 12 to 20 microns. It should be noted that the above-mentioned sizes are only illustrative examples, and the size of the second main body in the embodiment of the present disclosure may be determined according to the size and resolution of the actual product.

[0130] For example, in some examples, such as Figure 6 As shown, the shape of the second main body 1122 is roughly hexagonal or elliptical, and the long axis of the hexagonal symmetry or the long axis of the ellipse is roughly parallel to the first direction. It should be noted that the above-mentioned "roughly parallel" means that the angle between the long axis of the hexagonal symmetry or the long axis of the ellipse and the first direction does not exceed 5 degrees.

[0131] It is worth noting that the embodiments of the present disclosure include but are not limited to this, and the shape of the second main body of the embodiments of the present disclosure may also be other long strips; in addition, when the shape of the second main body is approximately hexagonal or elliptical, and the long axis of symmetry of the hexagon or the long axis of the ellipse may not be parallel to the first direction, as long as the orthographic projection of the second anode on the plane where the signal line group is located overlaps with the two adjacent signal line groups.

[0132] For example, in some examples, such as Figure 6 As shown, the display substrate further includes a pixel defining layer 160, which is located on the side of the second anode 1120 away from the base substrate 101 and includes a second opening 162. The first sub-pixel 112 further includes a second light-emitting layer 1124, at least a portion of which is located in the second opening 162; the area defined by the second opening 162 is a second effective light-emitting area 1125. The second anode 1120 can drive the second light-emitting layer 1124 to emit light.

[0133] For example, Figure 8As shown, the area of ​​the second effective light-emitting region 1125 may be slightly smaller than the area of ​​the second anode 1120, the shape of the second effective light-emitting region 1125 may be similar to the shape of the second main body 1122 of the second anode 1120, and the shortest distance between the edge of the second effective light-emitting region 1125 and the edge of the second main body 1122 is in the range of 1-5 microns.

[0134] It should be noted that the second light-emitting layer 1124 may include the electroluminescent layer itself and other functional layers located on both sides of the electroluminescent layer, such as a hole injection layer, a hole transport layer, an electron injection layer, and an electron transport layer.

[0135] For example, in some examples, such as Figure 8 As shown, the second sub-pixel 112 further includes a second cathode 1126 , and the second cathode 1126 is located on a side of the second light emitting layer 1125 away from the second anode 1122 .

[0136] For example, in some examples, such as Figure 6 As shown, each sub-pixel group 110 also includes a third sub-pixel pair 116; the third sub-pixel pair 116 includes two third sub-pixels 113; each third sub-pixel 113 includes a third anode 1130, and the two third anodes 1130 of the third sub-pixel pair 116 overlap with a signal line group 120 respectively, and the two signal line groups 120 overlapping with the two third anodes 1130 of the third sub-pixel pair 116 are adjacent, that is, two adjacent signal line groups 120. Fig. 9A FIG. 1 is a schematic diagram of the structure of another display substrate provided according to an embodiment of the present disclosure. Fig. 9A As shown, the third sub-pixel pair 116 is regarded as a whole. Since the two third anodes 1130 of the third sub-pixel pair 116 overlap with a signal line group 120 respectively, and the two signal line groups 120 overlapped with the two third anodes 1130 of the third sub-pixel pair 116 are adjacent, two protrusions 179 are formed at the positions where the two third anodes 1130 of the third sub-pixel pair 116 overlap with the two adjacent signal line groups 120. The two protrusions 179 can reduce the asymmetry of the light emission of the third sub-pixel pair 116, or even eliminate the asymmetry of the light emission of the third sub-pixel pair 116, thereby further improving or even eliminating the color deviation phenomenon generated when observing from the left and right sides of the normal of the display substrate at the same angle as the normal of the display substrate.

[0137] For example, in some examples, such as Figure 6 As shown, the orthographic projection of the signal line 1200 in the signal line group 120 overlapping the third anode 1130 on the base substrate 101 extends in the second direction and passes through the orthographic projection of the third anode 1130 on the base substrate 101 .

[0138] For example, in some examples, such as Figure 6As shown, the third sub-pixel 113 includes a third effective light-emitting area 1135, the third anode 1130 includes a third main body 1132, the third main body 1132 at least partially overlaps with the third effective light-emitting area 1135, and the two signal line groups 120 overlapping with the two third anodes 1130 of the third sub-pixel pair 116 are substantially axially symmetrical about the third bisector of the center line of the two third main bodies 1132, and the third bisector is parallel to the second direction. At this time, Fig. 9A As shown, the two anodes 1130 or the two third effective light-emitting areas 1135 form two symmetrical protrusions 179 at the positions overlapping with the two adjacent signal line groups 120. The two protrusions 179 can further effectively reduce the asymmetry of the light emission of the third sub-pixel pair 116, or even eliminate the asymmetry of the light emission of the third sub-pixel pair 116, thereby further improving or even eliminating the color deviation phenomenon generated when observing from the left and right sides of the normal line of the display substrate at the same angle as the normal line of the display substrate.

[0139] For example, in some examples, such as Figure 6 As shown, each signal line group 120 includes two signal lines 1200, and the two third anodes 1130 of the third sub-pixel pair 116 overlap with the two signal lines 1200 in one signal line group 1200, respectively, and the two signal line groups 120 overlapping with the two third anodes 1130 of the third sub-pixel pair 116 are adjacent. For example, in some examples, Figure 6 As shown, a plurality of sub-pixel groups 110 are arranged along the second direction to form a plurality of sub-pixel group columns 210, and are arranged along the first direction to form a plurality of sub-pixel group rows 310. Two adjacent sub-pixel group columns 210 are arranged at a 1 / 2 pitch offset, and are arranged at a 1 / 2 pitch offset along the second direction. The above pitch is equal to the distance between the centers of two first sub-pixels 111 in two adjacent sub-pixel groups 110 in the second direction. In each sub-pixel group 110, the first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel pair 116 are arranged along the second direction, and the two third sub-pixels 113 in the third sub-pixel pair 116 are arranged along the first direction. In other words, each sub-pixel group can be a repeating unit in the display substrate.

[0140] For example, in some examples, the first sub-pixel 111 is configured to emit light of a first color, the second sub-pixel 112 is configured to emit light of a second color, and the third sub-pixel 113 is configured to emit light of a third color.

[0141] For example, in some examples, the first color is blue, the second color is red, and the third color is green. Thus, the display substrate is an arrangement structure of red, green, and blue sub-pixels. Of course, the embodiments of the present disclosure include but are not limited to this. The first color, the second color, and the third color may also be other colors.

[0142] For example, in some examples, such as Figure 6 As shown, the shape of the third main body portion 1132 is substantially a pentagon, and the right-angled sides of the pentagon are substantially parallel to the second direction.

[0143] For example, in some examples, the size of the third body portion 1132 in the first direction ranges from 23 to 27 microns, and the size of the third body portion 1132 in the second direction ranges from 18 to 22 microns.

[0144] For example, in some examples, such as Fig. 9A As shown, when the sub-pixel group 110 includes a third sub-pixel 113, the third sub-pixel 113 also includes a third light-emitting layer 1134; at this time, the pixel defining layer 160 also includes a third opening 163, the third opening 163 exposes the third anode 1130, at least a portion of the third light-emitting layer 1134 is located in the third opening 163 and covers the exposed portion of the third anode 1130, and the area defined by the third opening 163 is the third effective light-emitting area 1135 of the third sub-pixel 113.

[0145] It should be noted that the area of ​​the third main body 1132 of the third anode 1130 may be slightly larger than the area of ​​the third light-emitting layer 1134. In addition, the third light-emitting layer 1134 may include the electroluminescent layer itself and other functional layers located on both sides of the electroluminescent layer, such as a hole injection layer, a hole transport layer, an electron injection layer, and an electron transport layer.

[0146] Fig. 9B FIG. 1 is a schematic diagram of the structure of another display substrate provided according to an embodiment of the present disclosure. Fig. 9B As shown, two third effective light-emitting areas 1135 in a third sub-pixel pair 116 can share one third opening 163, that is, the area of ​​the third opening 163 is slightly larger than the areas of the two third effective light-emitting areas 1135, and the area of ​​the light-emitting layer in the third opening 1135 can be slightly larger than the areas of the two third main bodies 1132. In this case, the third effective light-emitting area 1135 can be the overlapping area of ​​the third opening 163 and the third main body 1132.

[0147] For example, in some examples, such as Fig. 9B As shown, each third sub-pixel 113 further includes a third cathode 1136 , and the third cathode 1136 is located on a side of the third light-emitting layer 1135 away from the third anode 1132 .

[0148] It should be noted that the above-mentioned effective light-emitting areas (for example, the first effective light-emitting area, the second effective light-emitting area or the third effective light-emitting area) are generally designed to be regular shapes, such as the above-mentioned hexagon, pentagon, or ellipse. However, in the actual manufacturing process, the shape of the effective light-emitting area formed generally has a certain deviation from the regular shape designed above. For example, the corners of the above-mentioned regular shape may become rounded, so the shape of the above-mentioned effective light-emitting areas (for example, the first effective light-emitting area, the second effective light-emitting area or the third effective light-emitting area) can be a rounded shape. In addition, the shape of the effective light-emitting area actually manufactured may also have other changes from the designed shape. For example, the shape of the effective light-emitting area designed as a hexagon may become an approximate ellipse in actual manufacturing.

[0149] For example, in some examples, such as Figure 6 As shown, when the first sub-pixel 111 is a blue sub-pixel, the second sub-pixel 112 is a red sub-pixel, and the third sub-pixel 113 is a green sub-pixel, the area of ​​the first light-emitting layer 1114 of the first sub-pixel 111 and the area of ​​the second light-emitting layer 1124 of the second sub-pixel 112 are both larger than the area of ​​the third light-emitting layer 1134 of the single third sub-pixel 113, and the area of ​​the first light-emitting layer 1114 of the first sub-pixel 111 is larger than the area of ​​the second light-emitting layer 1124 of the second sub-pixel 112.

[0150] An embodiment of the present disclosure provides a display substrate, such as Figure 6As shown, the display substrate includes: a base substrate 101 and a plurality of sub-pixel groups 110 and a plurality of signal line groups 120 arranged on the base substrate 101; the plurality of signal line groups 120 are arranged at intervals along a first direction, each signal line group 120 includes a first signal line 121 and a second signal line 122, the first signal line 121 and the second signal line 122 both extend along a second direction intersecting the first direction, in each signal line group 120, the first signal line 121 and the second signal line 122 are arranged in sequence, and the arrangement order of the first signal line 121 and the second signal line 122 in two adjacent signal line groups 120 is the same; the plurality of sub-pixel groups 110 are arranged along the second direction to form a plurality of sub-pixel group columns, and are arranged along the first direction to form a plurality of sub-pixel group rows, two adjacent sub-pixel group columns are staggered by 1 / 2 pitch, the pitch is equal to the distance between the centers of the two first sub-pixels in the two adjacent sub-pixel groups in the second direction, and each sub-pixel group 1 10 includes a first sub-pixel 111, a second sub-pixel 112 and a third sub-pixel pair 116, the third sub-pixel pair 116 includes two third sub-pixels 113, in each sub-pixel group 110, the first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel pair 116 are arranged along the second direction, the two third sub-pixels 113 in the third sub-pixel pair 116 are arranged along the first direction, the first sub-pixel 111 includes a first anode 1110, the second sub-pixel 112 includes a second anode 1120, the third sub-pixel 113 includes a third anode 1130, the first anode 1110 overlaps with two adjacent signal line groups 120, the second anode 1120 overlaps with two adjacent signal line groups 120, the two third anodes 1130 of the third sub-pixel pair 116 overlap with one signal line group 120 respectively, and are adjacent to the two signal line groups 120 overlapped with the two third anodes 1130 of the third sub-pixel pair 116. An embodiment of the present disclosure also provides a display device. The display device includes the above-mentioned display substrate. Therefore, the display device also effectively reduces the asymmetry of the light emission of the anode and the light-emitting layer on the anode of each sub-pixel (for example, the above-mentioned first anode and the first light-emitting layer on the first anode, the second anode and the second light-emitting layer on the second anode, and the third anode and the first light-emitting layer on the third anode), and even eliminates the asymmetry of the light emission of the effective light-emitting area, thereby improving or even eliminating the color shift phenomenon generated when observing from the left and right sides of the normal line of the display device at the same angle as the normal line of the display substrate, thereby improving the display quality and optimizing the user experience.

[0151] For example, in some examples, the display device may be any product or component with a display function, such as a smart phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, or the like.

[0152] An embodiment of the present disclosure also provides a display substrate. Figure 6 and 7As shown, the display substrate includes a base substrate 101, a plurality of sub-pixel groups 110 and a plurality of signal line groups 120 arranged on the base substrate 101. The plurality of signal line groups 120 are arranged in a first direction at intervals, and each signal line group 120 includes two signal lines 1200; the signal lines 1200 extend along a second direction intersecting the first direction. Each sub-pixel group 110 includes a blue sub-pixel 111 and a red sub-pixel 112, the blue sub-pixel 111 includes a first anode 1110, and the red sub-pixel 112 includes a second anode 1120, the first anode 1110 overlaps with four signal lines 1200 in two adjacent signal line groups 120, and the second anode 1120 overlaps with four signal lines 1200 in two adjacent signal line groups 120.

[0153] In the display substrate provided by the embodiment of the present disclosure, the first anode 1110 of the blue sub-pixel 111 and the second anode 1120 of the red sub-pixel 112 overlap with four signal lines 1200 in two adjacent signal line groups 120 at the same time. At this time, even if the first anode 1110 forms a protrusion at the position overlapping with the signal line group 120, the first anode 1110 will form two protrusions at the position overlapping with the two adjacent signal line groups 120, and the two protrusions can reduce the asymmetry of the light emission of the first anode 1110 and the light-emitting layer on the first anode 1110, and even eliminate the asymmetry of the light emission of the first anode 1110 and the light-emitting layer on the first anode 1110, thereby improving or even eliminating the color shift phenomenon generated when observing from the left and right sides of the normal line of the display substrate at the same angle as the normal line of the display substrate. Similarly, even if the second anode 1120 forms a protrusion at the position overlapping with the signal line group 120, the second anode 1120 will form two protrusions at the position overlapping with two adjacent signal line groups 120. The two protrusions can reduce the asymmetry of the light emitted by the second anode 1120 and the light-emitting layer on the second anode 1120, and can even eliminate the asymmetry of the light emitted by the second anode 1110 and the light-emitting layer on the second anode 1120, thereby further improving or even eliminating the color deviation phenomenon generated when observing from the left and right sides of the normal to the display substrate at the same angle as the normal to the display substrate.

[0154] For example, in some examples, the two signal lines 1200 included in each signal line group 120 may be a data line 121 and a power line 122, the data line is used to transmit or write data, and the power line is used to transmit a power line of a driving voltage. Due to the large thickness of the data line and the power line, the flat layer covering the data line and the power line cannot completely flatten the display substrate, resulting in uneven anodes on the flat layer and uneven light-emitting layers on the anode, so that bulges appear on the anode and the light-emitting layers on the anode. The display substrate provided by the embodiment of the present disclosure can eliminate the asymmetry of the light emission of the light-emitting layers on the first anode and the second anode by making the first anode and the second anode overlap with the four signal lines in the two adjacent signal line groups at the same time, thereby further improving or even eliminating the color shift phenomenon caused when observing from the left and right sides of the normal line of the display substrate at the same angle as the normal line of the display substrate.

[0155] For example, in some examples, such as Figure 6 As shown, the orthographic projections of the four signal lines 1200 overlapping with the first anode 1110 on the substrate substrate 101 extend in the second direction and pass through the orthographic projection of the first anode 1110 on the substrate substrate 101, and the orthographic projections of the four signal lines 1200 overlapping with the second anode 1120 on the substrate substrate 101 extend in the second direction and pass through the orthographic projection of the second anode 1120 on the substrate substrate 101.

[0156] For example, in some examples, such as Figure 6 As shown, each sub-pixel group 110 also includes a green sub-pixel pair 116, each green sub-pixel pair 116 includes two green sub-pixels 113, each green sub-pixel 113 includes a third anode 1130, and the two third anodes 1130 of the green sub-pixel pair 116 overlap with two signal lines 1200 in a signal line group 120, respectively, and are adjacent to two signal line groups 120 overlapping with the two third anodes 1130 of the third sub-pixel pair 116. At this time, the third sub-pixel pair 116 is regarded as a whole. Since the two third anodes 1130 of the third sub-pixel pair 116 overlap with a signal line group 120 respectively, and the two signal line groups 120 overlapped with the two third anodes 1130 of the third sub-pixel pair 116 are adjacent, two protrusions are formed at the positions where the two third anodes 1130 of the third sub-pixel pair 116 overlap with the two adjacent signal line groups 120. The two protrusions can reduce the asymmetry of the light emission of the third sub-pixel pair 116, or even eliminate the asymmetry of the light emission of the third sub-pixel pair 116, thereby further improving or even eliminating the color deviation phenomenon caused by observing from the left and right sides of the normal of the display substrate at the same angle as the normal of the display substrate.

[0157] At least one embodiment of the present disclosure further provides a display substrate. Figure 6 and 7As shown, the display substrate includes a base substrate 101, a plurality of sub-pixel groups 110 and a plurality of signal line groups 120 disposed on the base substrate 101. The plurality of signal line groups 120 are arranged at intervals along a first direction, and each signal line group 120 includes a first signal line 121 and a second signal line 122, and the first signal line 121 and the second signal line 122 extend along a second direction intersecting the first direction. Each sub-pixel group 110 includes a first sub-pixel 111, the first sub-pixel 111 includes a first anode 1110 and a first effective light-emitting area 1115, the first anode 1110 includes a first main body 1112, the first main body 1112 and the first effective light-emitting area 1115 at least partially overlap, the size of the interval between two adjacent signal line groups 120 in the first direction is 8-10 times the size of the first signal line 121 in the first direction; the size of the first main body 1112 in the first direction is 15-17 times the size of the first signal line 121 in the first direction, and the size of the first main body 1112 in the second direction is 9-11 times the size of the first signal line 121 in the first direction. Since the size of the first main body 1112 in the first direction is 15-17 times the size of the first signal line 121 in the first direction, two adjacent signal line groups 120 can be covered. At this time, even if the first anode 1110 forms a protrusion at the position overlapping with the signal line group 120, the first anode 1110 will form two protrusions at the position overlapping with two adjacent signal line groups 120. The two protrusions can reduce the asymmetry of the light emission of the first anode 1110 and the light-emitting layer on the first anode 1110, and can even eliminate the asymmetry of the light emission of the first anode 1110 and the light-emitting layer on the first anode 1110, thereby improving or even eliminating the color deviation phenomenon caused when observing from the left and right sides of the normal to the display substrate at the same angle as the normal to the display substrate.

[0158] For example, in some examples, a ratio of a size of the first main body portion 1112 in the first direction to a size of the first main body portion 1112 in the second direction is γ1, and a value range of γ1 is 1.5-1.7.

[0159] For example, in some examples, each sub-pixel group 110 further includes a second sub-pixel 112, the second sub-pixel 112 includes a second anode 1120 and a second effective light-emitting area 1125, the second anode 1120 includes a second main body 1122, the second main body 1122 overlaps the second effective light-emitting area 1125, the size of the interval between two adjacent signal line groups 120 in the first direction is 8-10 times the size of the first signal line 121 in the first direction, the size of the second main body 1122 in the first direction is 12-14 times the size of the first signal line in the first direction, and the size of the second main body in the second direction is 4-6 times the size of the first signal line in the first direction. Since the size of the second main body 1122 in the first direction is 12-14 times the size of the first signal line 121 in the first direction, two adjacent signal line groups 120 can be covered. At this time, even if the second anode 1120 forms a protrusion at the position overlapping with the signal line group 120, the second anode 1120 will form two protrusions at the position overlapping with the two adjacent signal line groups 120. The two protrusions can reduce the asymmetry of the light emitted by the second anode 1120 and the light-emitting layer on the second anode 1120, and can even eliminate the asymmetry of the light emitted by the second anode 1120 and the light-emitting layer on the second anode 1120, thereby improving or even eliminating the color deviation phenomenon caused when observing from the left and right sides of the normal to the display substrate at the same angle as the normal to the display substrate.

[0160] For example, in some examples, a ratio of a size of the second main body portion 1122 in the first direction to a size of the second main body portion 1122 in the second direction is γ2, and a value range of γ2 is 2.2-2.6.

[0161] For example, in some examples, each subpixel group 110 also includes a third subpixel pair 116, each third subpixel pair 116 includes two third subpixels 113, each third subpixel 113 includes a third anode 1130 and a third effective light-emitting area 1135, the third anode 1130 includes a third main body 1132, the third main body 1132 at least partially overlaps with the third effective light-emitting area 1135, the interval between two adjacent signal line groups 120 in the first direction is 8-10 times the size of the first signal line 121 in the first direction, the size of the third main body 1132 in the first direction is 6-8 times the size of the first signal line 121 in the first direction, and the size of the third main body 1132 in the second direction is 7-9 times the size of the first signal line 121 in the first direction.

[0162] For example, in some examples, the size of the second signal line 122 in the first direction is 1.3-1.4 times the size of the first signal line 121 in the first direction.

[0163] For example, in some examples, the orthographic projection of the first effective light-emitting area 1115 on the substrate 101 falls within the orthographic projection of the first anode 1112 on the substrate 101, the shortest distance between the edge of the orthographic projection of the first effective light-emitting area 1115 on the substrate 101 and the edge of the orthographic projection of the first anode 1112 on the substrate 101 is in the range of 1-3 microns, and the orthographic projection of the second effective light-emitting area 1125 on the substrate 101 falls between the orthographic projection of the second anode 1122 on the substrate 101. The shortest distance between the edge of the orthographic projection of the second effective light-emitting area 1125 on the substrate substrate 101 and the edge of the orthographic projection of the second anode 1122 on the substrate substrate 101 is in the range of 1-3 microns, the orthographic projection of the third effective light-emitting area 1135 on the substrate substrate 101 falls within the orthographic projection of the third anode 1132 on the substrate substrate 101, and the shortest distance between the edge of the orthographic projection of the third effective light-emitting area 1135 on the substrate substrate 101 and the edge of the orthographic projection of the third anode 1132 on the substrate substrate 101 is in the range of 1-3 microns.

[0164] For example, in some examples, the first sub-pixel is a blue sub-pixel, the second sub-pixel is a red sub-pixel, and the third sub-pixel is a green sub-pixel. At least one embodiment of the present disclosure further provides a display substrate. Figure 6 and 7 As shown, the display substrate includes a base substrate 101, a plurality of sub-pixel groups 110 and a plurality of signal line groups 120 disposed on the base substrate 101. The plurality of signal line groups 120 are arranged at intervals along a first direction, and each signal line group 120 includes a first signal line 121 and a second signal line 122, and the first signal line 121 and the second signal line 122 extend along a second direction intersecting the first direction. Each sub-pixel group 110 includes a blue sub-pixel 111 and a red sub-pixel 112, the blue sub-pixel 111 includes a first anode 1110 and a first effective light-emitting area 1115, the red sub-pixel 112 includes a second anode 1120 and a second effective light-emitting area 1125, the first anode 1110 includes a first main body 1112, the first main body 1112 and the first effective light-emitting area 1115 at least partially overlap, the second anode 1120 includes a second main body 1122, the second main body 1122 and the second effective light-emitting area 1125 at least partially overlap, the orthographic projection of the first main body 1112 on the substrate 101 is substantially in the shape of a long strip, the extension direction of the first main body 1112 intersects with the second direction, the orthographic projection of the second main body 1122 on the substrate 101 is substantially in the shape of a long strip, and the extension direction of the second main body 1122 intersects with the second direction. It should be noted that the extension direction of the first main body and the extension direction of the second main body may be the same as or different from the first direction.

[0165] In the display substrate provided in the embodiment of the present disclosure, since the extension direction of the first main body 1112 of the first anode 1110 of the first sub-pixel 111 intersects with the second direction, the first main body 1112 can cover two adjacent signal line groups 120; at this time, even if the first anode 1110 forms a protrusion at the position overlapping with the signal line group 120, the first anode 1110 will form two protrusions at the position overlapping with the two adjacent signal line groups 120, and the two protrusions can reduce the asymmetry of the light emission of the first anode 1110 and the light-emitting layer on the first anode 1110, and can even eliminate the asymmetry of the light emission of the first anode 1110 and the light-emitting layer on the first anode 1110, thereby improving or even eliminating the color deviation phenomenon generated when observing from the left and right sides of the normal of the display substrate at the same angle as the normal of the display substrate. Similarly, since the extension direction of the second main body 1122 of the second anode 1120 of the second sub-pixel 112 intersects with the second direction, the second main body 1112 can cover two adjacent signal line groups 120; at this time, even if the second anode 1120 forms a protrusion at the position overlapping with the signal line group 120, the second anode 1120 will form two protrusions at the position overlapping with the two adjacent signal line groups 120, and the two protrusions can reduce the asymmetry of the light emission of the second anode 1120 and the light-emitting layer on the second anode 1120, and can even eliminate the asymmetry of the light emission of the second anode 1110 and the light-emitting layer on the second anode 1120, thereby further improving or even eliminating the color deviation phenomenon caused when observing from the left and right sides of the normal to the display substrate at the same angle as the normal to the display substrate.

[0166] For example, in some examples, such as Figure 6 As shown, the extension direction of the first main body 1112 is substantially perpendicular to the second direction, and the extension direction of the second main body 1122 is substantially perpendicular to the second direction. At this time, when the lengths of the first main body 1112 and the second main body 1122 (the dimensions in the extension direction thereof) are large enough, it can be ensured that the first main body 1112 can cover two adjacent signal line groups 120, and the second main body 1122 can cover two adjacent signal line groups 120. It should be noted that the above-mentioned "substantially perpendicular" includes the case where the angle between the extension direction of the first main body or the second main body and the second direction is in the range of 85-95 degrees.

[0167] For example, in some examples, such as Figure 6 As shown, the first direction is perpendicular to the second direction. At this time, the extension direction of the first main body 1112 may be substantially parallel to the first direction, and the extension direction of the second main body 1122 may be substantially parallel to the first direction. It should be noted that the above-mentioned "substantially parallel" includes the case where the angle between the extension direction of the first main body or the second main body and the first direction is in the range of 0-5 degrees.

[0168] For example, in some examples, the size of the interval between two adjacent signal line groups 120 in the first direction is 8-10 times the size of the first signal line 121 in the first direction; the size of the first body portion 1112 in the first direction is 15-17 times the size of the first signal line 121 in the first direction, and the size of the first body portion 1112 in the second direction is 9-11 times the size of the first signal line 121 in the first direction. Since the size of the first body portion 1112 in the first direction is 15-17 times the size of the first signal line 121 in the first direction, two adjacent signal line groups 120 can be covered. At this time, even if the first anode 1110 forms a protrusion at the position overlapping with the signal line group 120, the first anode 1110 will form two protrusions at the position overlapping with two adjacent signal line groups 120. The two protrusions can reduce the asymmetry of the light emission of the first anode 1110 and the light-emitting layer on the first anode 1110, and can even eliminate the asymmetry of the light emission of the first anode 1110 and the light-emitting layer on the first anode 1110, thereby improving or even eliminating the color deviation phenomenon caused when observing from the left and right sides of the normal to the display substrate at the same angle as the normal to the display substrate.

[0169] For example, in some examples, the dimension of the first signal line 121 in the first direction is 3-4 micrometers.

[0170] For example, in some examples, the size of the interval between two adjacent signal line groups 120 in the first direction is 8-10 times the size of the first signal line 121 in the first direction, the size of the second body portion 1122 in the first direction is 12-14 times the size of the first signal line in the first direction, and the size of the second body portion in the second direction is 4-6 times the size of the first signal line in the first direction. Since the size of the second body portion 1122 in the first direction is 12-14 times the size of the first signal line 121 in the first direction, two adjacent signal line groups 120 can be covered. At this time, even if the second anode 1120 forms a protrusion at the position overlapping with the signal line group 120, the second anode 1120 will form two protrusions at the position overlapping with the two adjacent signal line groups 120. The two protrusions can reduce the asymmetry of the light emitted by the second anode 1120 and the light-emitting layer on the second anode 1120, and can even eliminate the asymmetry of the light emitted by the second anode 1120 and the light-emitting layer on the second anode 1120, thereby improving or even eliminating the color deviation phenomenon caused when observing from the left and right sides of the normal to the display substrate at the same angle as the normal to the display substrate.

[0171] For example, in some examples, the size of the second signal line 122 in the first direction is 1.3-1.4 times the size of the first signal line 121 in the first direction. That is, the width of the second signal line 122 is relatively wide, thereby facilitating the transmission of the driving voltage.

[0172] For example, in some examples, each subpixel group 120 also includes a green subpixel pair 116, each green subpixel 116 pair includes two green subpixels 113, each green subpixel 113 includes a third anode 1130 and a third effective light-emitting area 1135, the third anode 1130 includes a third main body 1132, the third main body 1132 at least partially overlaps with the third effective light-emitting area 1135, and the third main body 1132 covers a signal line group 120 and is adjacent to two signal line groups 120 that overlap with the two third main bodies 1132 of the green subpixel pair 116. At this time, the third sub-pixel pair 116 is regarded as a whole. Since the two third anodes 1130 of the third sub-pixel pair 116 overlap with a signal line group 120 respectively, and the two signal line groups 120 overlapped with the two third anodes 1130 of the third sub-pixel pair 116 are adjacent, two protrusions are formed at the positions where the two third anodes 1130 of the third sub-pixel pair 116 overlap with the two adjacent signal line groups 120. The two protrusions can reduce the asymmetry of the light emission of the third sub-pixel pair 116, or even eliminate the asymmetry of the light emission of the third sub-pixel pair 116, thereby further improving or even eliminating the color deviation phenomenon caused by observing from the left and right sides of the normal of the display substrate at the same angle as the normal of the display substrate.

[0173] For example, in some examples, the size of the interval between two adjacent signal line groups 120 in the first direction is 8-10 times the size of the first signal line 121 in the first direction, the size of the third main body 1132 in the first direction is 6-8 times the size of the first signal line 121 in the first direction, and the size of the third main body 1132 in the second direction is 7-9 times the size of the first signal line 121 in the first direction. At this time, in one third sub-pixel pair 116, the size of the two third main bodies 1132 in the first direction is at least 12-16 times the size of the first signal line 121 in the first direction, so that they can overlap with the two adjacent signal line groups 120.

[0174] For example, in some examples, the orthographic projection of the first effective light-emitting area 1115 on the substrate substrate 101 falls within the orthographic projection of the first anode 1112 on the substrate substrate 101, the shortest distance between the edge of the orthographic projection of the first effective light-emitting area 1115 on the substrate substrate 101 and the edge of the orthographic projection of the first anode 1112 on the substrate substrate 101 is in the range of 1-3 micrometers, the orthographic projection of the second effective light-emitting area 1125 on the substrate substrate 101 falls within the orthographic projection of the second anode 1122 on the substrate substrate 101, and the second effective light-emitting area 1125 on the substrate substrate 101 falls within the orthographic projection of the second anode 1122 on the substrate substrate 101. The shortest distance between the edge of the orthographic projection of the effective light-emitting area 1125 on the substrate substrate 101 and the edge of the orthographic projection of the second anode 1122 on the substrate substrate 101 is in the range of 1-3 microns, the orthographic projection of the third effective light-emitting area 1135 on the substrate substrate 101 falls within the orthographic projection of the third anode 1132 on the substrate substrate 101, and the shortest distance between the edge of the orthographic projection of the third effective light-emitting area 1135 on the substrate substrate 101 and the edge of the orthographic projection of the third anode 1132 on the substrate substrate 101 is in the range of 1-3 microns.

[0175] At least one embodiment of the present disclosure further provides a display substrate, such as Figure 6 As shown, it includes: a base substrate 101; a plurality of sub-pixel groups 110; and a plurality of signal line groups 120, which are arranged at intervals along a first direction, each signal line group 120 includes a first signal line 121 and a second signal line 122, and the first signal line 121 and the second signal line 122 both extend along a second direction intersecting the first direction. In each signal line group 120, the first signal line 121 and the second signal line 122 are arranged in sequence, and the arrangement order of the first signal line 121 and the second signal line 122 in two adjacent signal line groups 120 is the same, and each sub-pixel group 120 includes a first sub-pixel 111, and the first sub-pixel 111 includes a first anode 1110, and the first anode 1110 overlaps with two adjacent signal line groups 120.

[0176] For example, in some examples, such as Figure 6 As shown, two adjacent signal line groups 120 include a first signal line group 1201 and a second signal line group 1202 arranged along a first direction, the first signal line 121 in the first signal line group 1201 is located on a side of the second signal line 122 away from the second signal line group 1202, and the first signal line 121 in the second signal line group 1202 is located on a side of the second signal line 122 close to the first signal line group 1201.
